dont worry, it shouldnt be a problem. My motronic couldnt hear knock either. Knock sensors wont save you. A good map will

Ok, thats a good one
...You really feel striongly about a good MAP and in motronic at WOT is does go the MAP and my car with my MAP goes very well. But I couldnt get all the issues like aircon compensation, idling and a few other issues sorted so went with 034 chip set. But it cant compare power and torque wise to my own MAP, but is far nice to drive as its sorted properly for drivability...Now i want best of both world

To get VEMS to run properly will involve MUCH more work than motronic. And if you want the driveability to be good, then you will need a load-bearing dyno and then lots and lots of finetuning afterwards.
Aftermarket ECU management is not a magic bullet.Comment

i agree. i had and still am working on vems for many months. Im close to being perfect for my liking, but i can say that with vems i solved some issues i had with motronic, but gained some different with it. Hopefully with the latest update i shall solve those as well, and be happier.
Having said that, i havent tuned the car on a dyno, and therefore im to blame for part of the issues i have with vems. Otherwise its a nice piece of kit!Comment

the problem with motronic is understanding how it works and also the purchase of equipment to be able to manipulate the maps, whereas vems has easy values to understand what you are changing and are universal.So yes, when compared to a tuner who tunes motronic, yes vems is more difficult. But if you take vems to a person who does any kind of mapping, they can tune it for you.Comment

Agree...
And it's not because of equipment price.
Compared to wasting months of your life sitting in IDA Pro, 300 EUR is nothing
Since VEMS offers a plug and play variant and there are plenty of basemaps around, it is always a good option if you don't have the ability to get your stock ECU tuned or if the level of power exceeds what the stock ECU can handle.Comment

Would not the equivalent be a RT-Emulator??? :-)Agree...

my vies on WB02.
use it only up to about 80% throttle or 0.4 bar (spring pressure) or so.
yes you can use it all the time but lets put into prospective the amount of R & D on bosch me or wheatever versus vems. maybe if you go motec or anothe rvery high level ecu its not too bad.
theres a beauty in simplicity guys.Comment

Yeah, there is a ton of logic in the newer Motronics to determine whether the lambda is going bad. It cross-references readings from many sensors. Not to mention newer ones have multiple sensors etc.
It is correct, that if you run closed loop all the time and your wideband sensor goes bad, and your ECU has no protection routines, your AFR will be totally wrong.Comment
